Its common for the pipes where they meet the flexies to corrode, due to salt/rain etc.

You can just get a copper pipe made up to length and you bend to shape, very easy and they are a lot better than the factory stell items, with one downside (which is the reason i won't have them):

They look pants because you can't get them to look nice and straight etc (im a fussy cunt)
